24 June 2005. Summary of changes for version 20050624:
1) ACPI CA Core Subsystem:
Modified the new OSL cache interfaces to use ACPI_CACHE_T as the type for the host-defined cache object. This allows the OSL implementation to define and type this object in any manner desired, simplifying the OSL implementation. For example, ACPI_CACHE_T is defined as kmem_cache_t for Linux, and should be defined in the OS-specific header file for other operating systems as required.
Changed the interface to AcpiOsAcquireObject to directly return the requested object as the function return (instead of ACPI_STATUS.) This change was made for performance reasons, since this is the purpose of the interface in the first place. AcpiOsAcquireObject is now similar to the AcpiOsAllocate interface.
Implemented a new AML debugger command named Businfo. This command displays information about all devices that have an associate _PRT object. The _ADR, _HID, _UID, and _CID are displayed for these devices.
Modified the initialization sequence in AcpiInitializeSubsystem to call the OSL interface AcpiOslInitialize first, before any local initialization. This change was required because the global initialization now calls OSL interfaces.
Enhanced the Dump command to display the entire contents of Package objects (including all sub-objects and their values.)
Restructured the code base to split some files because of size and/or because the code logically belonged in a separate file. New files are listed below. All makefiles and project files included in the ACPI CA release have been updated.
utilities/utcache.c /* Local cache interfaces */
utilities/utmutex.c /* Local mutex support */
utilities/utstate.c /* State object support */
interpreter/parser/psloop.c /* Main AML parse loop */
Code and Data Size: Current and previous core subsystem library sizes are shown below. These are the code and data sizes for the acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and these values do not include any ACPI driver or OSPM code. The debug version of the code includes the debug output trace mechanism and has a much larger code and data size. Note that these values will vary depending on the efficiency of the compiler and the compiler options used during generation.
Previous Release:
Non-Debug Version: 78.3K Code, 11.6K Data, 89.9K Total
Debug Version: 164.0K Code, 69.1K Data, 233.1K Total
Current Release:
Non-Debug Version: 78.6K Code, 11.5K Data, 90.1K Total
Debug Version: 165.2K Code, 69.6K Data, 234.8K Total
2) iASL Compiler/Disassembler:
Fixed a regression introduced in version 20050513 where the use of a Package object within a Case() statement caused a compile time exception. The original behavior has been restored (a Match() operator is emitted.)
